Abstract

An 87-year-old man with a history of prior Billroth II surgery for bleeding peptic ulcer presents with melanic stools from outside hospital (OSH). A radionuclide study (tagged red blood cell, TRBC scan) was performed which showed active colonic bleed for which a colectomy was offered, but the patient refused. He was transferred to our facility for an alternative procedure. A CT angiogram was performed which did not show any extravasation. This led to an EGD which showed a duodenal polyp, for which snare cautery polypectomy was performed. Biopsy reviewed a benign polypoid duodenal vascular malformation. Due to the false localization of left-sided colonic bleed, a colonoscopy was performed which only showed conducted blood from the possible source being a duodenal polyp.
